Hi Mike I belive the 331 cid is much better also as for heavy metal it i not nessary. The balancing can be done exterally w/28or50oz. balancer&flywheel unless you want to pay for the extra expence. Also with the 347cid. you have to clearence the block for the rods. I have built a # of 331`s with the eagle kit with our cam& eldbrock peformer RPM heads,victor Jr. manifold&deamon carb. It makes 425HP any questions call 513-738-5001 ask for Eric;performance eng.
